Multiple Sclerosis (MS)

Researchers are investigating how balance and walking abilities relate to detailed movement measurements in people with Multiple Sclerosis MS. This observational study focuses on understanding the connection between clinical tests of function and objective biomechanical data. The goal is to identify which movement characteristics best reflect balance, gait, and physical performance challenges faced by individuals with MS. Participants will attend a single laboratory session where they undergo biomechanical analysis using the Vicon motion capture system. They will complete functional assessments of balance, gait, and physical performance, as well as questionnaires about fear of falling and fatigue. Spasticity in the lower limbs will also be assessed during this visit. During the session, participants will perform tests such as the mini-BESTest for balance, Functional Gait Assessment, Short Physical Performance Battery, and a 2-minute walk test. Questionnaires like the Fall Efficacy Scale and Fatigue Severity Scale will be completed. Researchers will analyze these collected data to explore how biomechanical and functional measures relate, aiming to improve assessment tools for MS rehabilitation.

Researchers are evaluating a new, affordable way to monitor people with multiple sclerosis MS using patient-recorded selfie videos. This study aims to see if videos collected remotely on a mobile phone can provide the same walking and speech information as traditional in-person visits. The goal is to create a low-burden, patient-centered method that can be used widely and easily by diverse people with MS. Participants will record five short selfie videos at home during baseline, 3 months, 6 months, and 12 months. They will also attend in-person visits at baseline, 6 months, and 12 months for additional data collection. These videos capture daily activities like walking and talking, using the participants own device such as a smartphone, tablet, or computer without special software. During the study, participants will undergo several assessments including video uploads and in-person evaluations lasting about 15 minutes for video collection and one hour for in-person visits. Researchers will measure how well video data matches standard MS functional tests, the usability of the video method, and its ability to detect subtle changes over time. The study lasts one year and aims to improve remote monitoring for people living with MS.

The 100-Year Human Aging Study is a long-term observational research project enrolling adult participants to undergo detailed multi-system health screenings and follow them throughout their lives until death. The study aims to identify which health measurements taken at enrollment and repeatedly over time can predict overall mortality, cause-specific death, serious diseases, and functional disability. It addresses the current lack of validated longevity measures by generating data on how various physiological and cognitive functions relate to aging outcomes. Participants undergo a comprehensive clinical screening that includes tests of cardiorespiratory fitness, strength, mobility, neurocognitive performance, sensory functions, and metabolic health. Structural imaging assessments like DEXA scans, echocardiography, electrocardiography, spirometry, retinal photography, and vascular ultrasound are performed. Laboratory tests and detailed medical, social, and environmental histories are also collected. The study allows participation from single tests up to a full two-visit screening, with repeat testing encouraged to track health changes over time. Throughout the study, participants receive individualized reports with investigational estimates of biological age and predicted mortality risks, which are being evaluated against actual health outcomes. Researchers collect data continuously on mortality, disease occurrence, disability, and health behavior changes. The study involves ongoing follow-up with periodic assessments and aims to preserve all collected data for future analyses, with participant involvement potentially spanning their entire lifespan.

This research aims to compare a new spinal cord imaging technique called the 3D OPTIMIZED WMN MPRAGE sequence with conventional MRI sequences for people with multiple sclerosis. Multiple sclerosis is a common inflammatory disease affecting the central nervous system, often causing spinal cord damage that leads to symptoms like sensory loss, pain, weakness, and bladder or bowel problems. Imaging the spinal cord is important for diagnosis and prognosis, but current methods have limitations in detecting lesions accurately. The study involves scanning patients at the cervical and thoracic levels of the spinal cord using both conventional MRI sequences including 2D sagittal T2 FSE, 2D sagittal STIR, 2D sagittal PSIR, and 3D MPRAGE and the new 3D OPTIMIZED WMN MPRAGE sequence. At the cervical level, the new sequence will be acquired in sagittal and axial views, while at the thoracic level it will be acquired sagittally. This comparison will help assess whether the new sequence provides better detection of spinal cord lesions. Participants will undergo MRI scans at one visit where researchers will evaluate the number and volume of lesions, presence of artifacts, contrast quality, and the relation of lesions to the patients disability. The study will also measure sensitivity, positive predictive value, and reproducibility of the new imaging method. The total participation time corresponds to the imaging session on day one, with no long-term follow-up reported.

This research focuses on elderly patients hospitalized in Continuing and Rehabilitation Care Units, many of whom suffer from neurodegenerative diseases and need personalized rehabilitation care. The study evaluates the use of ergonomic cutlery handles tailored to patients hand grip ability, aiming to improve their autonomy during meals and potentially reduce malnutrition risks. These custom handles are made using 3D printing technology, offering a lightweight and inexpensive alternative to standard adapted cutlery. Participants will start with a functional and joint assessment of their hand to determine the optimal diameter for the cutlery handles 25, 30, 35, or 40 mm. Their autonomy in eating and the amount of food consumed will be measured at three lunch times before using the adapted handles Day 0, the first lunch using the handles Day 1, and after three days of use Day 3. Ergotherapists will also assess upper limb compensations during meals without and with the technical aid. Throughout the study, participants autonomy in eating is evaluated using the Katz scale, with additional assessments by ergotherapists and dieticians. The study tracks changes in food intake and physical compensations over three days, ending after the Day 3 assessments. The main outcome measured is patients food autonomy at Day 1, with secondary outcomes including autonomy and food intake at Day 3 and upper limb compensations. Participation lasts only through the initial assessment and the three-day intervention period.

Researchers are investigating the effects of deep brain stimulation DBS on brain function in patients with various neurological and psychiatric disorders, including Parkinsons disease, essential tremor, dystonia, depression, epilepsy, neuropathic pain, and Alzheimers disease. This prospective cohort study aims to use advanced MRI techniques, particularly functional MRI fMRI, to better understand how DBS influences brain circuits and to explore whether fMRI can aid clinical practice in managing DBS therapy. Participants in this study include patients who will undergo or have already undergone DBS electrode placement. The study involves performing structural MRI scans using 1.5 Tesla or 3 Tesla machines as well as resting state and task-based fMRI scans. DBS patients will be scanned while their devices are programmed at different stimulation settings, including switched off and switched on states. The fMRI results will be shared with clinicians to help guide DBS programming decisions. During the study, participants will have multiple brain scans from three months before DBS implantation to one year after. Researchers will assess brain areas activated by DBS, examine structural and functional brain connectivity through MRI, and monitor clinical outcomes. The study includes regular evaluations to observe how DBS impacts brain function over time, aiming to improve post-operative follow-up and optimize treatment for these patients.

Researchers are evaluating the use of 18FNIDF PET imaging to visualize abnormal tau protein pathology in the brains of living humans. This technique targets tau neurofibrillary tangles, which are linked to neurodegenerative diseases such as Alzheimers and other tauopathies. The study focuses on assessing the safety and diagnostic effectiveness of this imaging agent, which may offer advantages over existing tau PET tracers due to its stronger binding and lower off-target effects. Participants will receive a single intravenous injection of approximately 10 b1 3 mCi of 18FNIDF. Following the injection, a PETCT scan will be performed to capture images showing the distribution of the tracer in the brain. The study includes both healthy volunteers and patients with cognitive impairment or probable Alzheimers disease. There is only one main study period involving this single injection and imaging session. During the study, participants will be monitored for safety from the time of injection up to seven days afterward. The primary assessments include safety evaluation and measuring how the tracer spreads in the body during the PETCT scan on the injection day. Researchers will also evaluate the diagnostic performance of the imaging over a two-week period from enrollment to the end of imaging. Participants involvement is limited to the injection, scanning, and follow-up safety checks.

Researchers are investigating the specific targets of T cells involved in autoimmune diseases by studying tissues from patients with active organ inflammation caused by autoimmune conditions. The study aims to identify which T cells are activated and expanding in diseased tissues compared to blood or normal tissues. This information will help discover new peptide targets and their associated T cell receptors TCRs to develop potential new therapies for autoimmune diseases. Participants will provide tissue samples and matched blood samples during clinical procedures such as endoscopy, arthrocentesis, lumbar puncture, skin biopsy, bronchoscopy, or surgery, depending on their autoimmune condition. The study includes several groups covering diseases like Crohns disease, ulcerative colitis, celiac disease, ankylosing spondylitis, multiple sclerosis, scleroderma, systemic sclerosis, and other autoimmune diseases. Samples may come from excess clinical materials or research-specific biopsies, with the possibility of serial sampling over time. During the study, participants will undergo standard clinical procedures with collection of additional tissue or fluid samples and companion blood draws. Researchers will analyze these samples to identify peptide targets linked to disease-reactive T cells over a period of up to three years. The study includes comprehensive assessments of tissues and blood to understand T cell activity in autoimmune disorders, with monitoring of participant safety and no interventions beyond routine clinical care.

Researchers are studying the safety and effectiveness of CAR NK cells for treating relapsed or refractory B-cell related autoimmune diseases. This early phase 1 pilot study plans to enroll 15 patients to evaluate the safety, feasibility, and potential benefits of this treatment. The study also explores how well the CAR NK cells expand, persist, and deplete B cells in these patients. Participants will receive a pre-treatment of Fludarabine and Cyclophosphamide on days -5, -4, and -3, followed by an infusion of CAR NK cells. This is a single-group, open-label trial where all participants receive the study treatment. The trial monitors patients for adverse events and dose-limiting toxicities within the first 4 weeks and up to 52 weeks after infusion. During the study, participants will be closely monitored through clinical assessments and laboratory tests at multiple time points up to one year after treatment. Researchers will measure safety outcomes including adverse events and toxicities, as well as effectiveness outcomes like disease control and remission rates. The total study duration may last up to approximately three years, including follow-up to assess long-term safety and treatment effects.

Researchers are evaluating the safety, tolerability, and initial effectiveness of CD19BCMA-targeted CAR-T cell therapy in patients with refractory autoimmune diseases. This early exploratory, open-label, single-arm clinical study focuses on adults aged 18 to 70 who have autoimmune conditions that have not responded to standard treatments. The study aims to explore whether this new in vivo CAR-T therapy approach can control disease activity without prior lymphodepletion. Participants will receive an intravenous infusion of the CD19BCMA-targeted CAR-T lentiviral vector drug. After infusion, the CAR-T cells are produced directly inside the patients body. No lymphodepleting chemotherapy will be given before treatment. Following the infusion, participants will be monitored for safety and efficacy over a 24-month period to assess disease control and treatment tolerability. During the study, participants will undergo regular safety assessments to monitor adverse events at multiple time points including Day 28, and Months 2, 3, 6, 12, 18, and 24. Researchers will track the maximum tolerated dose within 28 days after infusion. Additional evaluations will include clinical and laboratory tests to assess disease response and patient health. The total participation length can be up to two years, allowing long-term observation of treatment effects and safety.
